A tissue repair matrix has an intricate pattern of loops, struts and bridges and is made of a super elastic alloy. The repair matrix includes hooks which improve the ingrowth when implanted and amorphic circles which provide rounded surfaces to the outer edges which made the repair matrix a-traumatic when implanted. When the repair matrix is cooled the molecular phase becomes martensitic which allows the tissue repair matrix to be compressed for easier insertion into a patient. When the tissue repair matrix is heated, the molecular phase changes to austenitic which causes the tissue repair matrix to expand to a size suitable for medical procedure.

Cette invention porte sur une matrice de réparation tissulaire qui possède un motif complexe de boucles, d'entretoises et de ponts, et qui est faite d'un alliage super élastique. La matrice de réparation comprend des crochets qui améliorent l'interposition lorsqu'ils sont implantés et les cercles amorphes qui fournissent des surfaces arrondies aux bordures externes qui rendent la matrice externe atraumatique lorsqu'ils sont implantés. Lorsque la matrice de réparation est refroidie, la phase moléculaire devient martensitique, ce qui permet à la matrice de réparation tissulaire d'être comprimée pour une introduction plus facile dans le corps d'un patient. Lorsque la matrice de réparation tissulaire est chauffée, la phase moléculaire se transforme en austénitique, ce qui amène la matrice de réparation tissulaire à se dilater jusqu'à une dimension appropriée pour un acte médical.
